Panchang in Ipameri, Goiás, Brazil Mon 26 Jul 2021

The Sankashti fast is broken at moonrise. Chaturthi runs from 18:24 on Mon 26 Jul to 17:58 on Tue 27 Jul, so it holds moonrise only on Mon 26 Jul, at 20:37. No text giving Sankashti Chaturthi’s time was found; moonrise is Tithika’s convention.

Sankashti Chaturthi: every date in Ipameri

The Moon gains on the Sun about 12° a day. Each 12° of lead is one tithi: 204°–216° is the 18th, Krishna Tritiya. A day takes the tithi in force at its sunrise, 06:41 here. Dwitiya ended at 19:34 Sun, before it. Tritiya ends at 18:24, when the lead reaches 216°. The lead passed 180° at the full moon of 23 Jul, so the Moon is waning: Krishna paksha.

The night of Sun 25 Jul ran from sunset 17:57 Sun to sunrise 06:41, 12 h 44 m. Cut into 15 muhurtas of 50 m, its 14th is Brahma Muhurta, the one before the last.

Daylight here, 06:41 to 17:57, splits into 8 choghadiyas of 1 h 24 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The night here, 17:57 to 06:41 Tue, splits into 8 choghadiyas of 1 h 35 m. Their names follow a fixed order that starts from the weekday, and each name is counted good, neutral or bad.

The fixed stars divide the Moon's path into 27 nakshatras of 13°20′, each in 4 padas of 3°20′. Shatabhisha spans 306°40′–320°00′; the Moon entered its pada 1 at 306°40′. It leaves at 01:43 Tue, for Purva Bhadrapada.

Add the Sun's and the Moon's places among the stars: 99.5° + 309.4° = 408.9°, one full turn and 48.9°. Past the turn, cut into 27 parts of 13°20′, it gives the yoga: 40°00′–53°20′ is the 4th, Saubhagya. It ends at 14:09, then Shobhana.

A karana is half a tithi: 6° of the Moon's lead, so the first half of Tritiya is Vanija and the second Vishti. Vanija runs until 06:54, when the lead reaches 210°; Vishti until 18:24.

A Hindu day runs from one sunrise to the next, not midnight to midnight. This one runs 06:41 to 06:41 Tue, so the hours after midnight still belong to Somawara.

An amanta month runs from new moon to new moon and takes its name from the rashi the Sun is in at the new moon that begins it: Mithuna gives Ashadha. The Sun enters Karka on 16 Jul, inside the month. The next new moon, 8 Aug, finds it in Karka and begins Shravana.

A purnimanta month runs from full moon to full moon, so its waning half comes first. It shares its name with the amanta month that its second half falls in: the new moon of 8 Aug, with the Sun in Karka, begins Shravana. Until then this Krishna paksha reads Shravana here, and Ashadha in the amanta count.

A samvat year begins with Chaitra, the month whose new moon finds the Sun in Meena: 11 Apr 2021, 23:30 Sun. Since then the Sun has moved 101.2° round the stars. Vikram Samvat numbers that year 2078; Shaka Samvat numbers it 1943.
